Specification of Letters Patentv utentcd 00135. 1915.

Application filed March 13. 1915. Serial No. 14.267.

Be it known that. I, Fawn Lanai-arr citizen of the United States of uier :a, and a resident of the borough of Brooklyn, county of Kings, city and State of Xevv York, have invented certain new and useful Improvements in Meters, of which the following is a specification.

My invention relates to improvements in meters, particularly meters of the mutating disk type. Such meters comprise a so-called measurin, chamber; having inlet and outlet ports, and having "within it a disk having a spherically-shaped bearing member at its denter, on which bearing member the disk rocks or nutates with a progressive wave like motion, under the influence of the fluid passing through the meter, but without rm tating; and by such motion the disk piston drives suitable registering mechanism. The measuring chamber is provided with a par tition termed in the art a diaphragm, extending from the periphery of the measuring chamber, at a point between the inlet and outlet parts thereof, to the said spherical bearing member of the piston, the piston be ing slotted to embrace this partition or diaphragm. I

'1he.measuring chamber is commonly inclosed within a'pressure easing itself having inlet and outlet ports, usually contained within projecting spuds. he said casing is commonly provided, internally, with in- Wardly projecting ribs, usually about 12Q apart, andthe measuring chamber is commonly provided exterior-1y, with corresponding ribs, the ribs of the casing and measuring chamber being, usually, nicely titted.

.In some cases, the adjacent surfaces of the ribs of the casing and measuring chamber are straight, while in other cases these surfaces are slightly conical or tapering. Both constructions are difficult of execution, the more so as, although it is desired that the measuring chamber shall be closely fitted within the casing, yetit is also necessary that the measuring chamber shall be readily introduced into, and readily removed from, the casing. Commonly, one of the three ribs of the casing is made quite broad, the corresponding rib of the measuring el amber bein of corresponding breadth and ecn tainmg either the inlet or the outletpcrt of that measuring chamber; the corresponding port (inlet or outlet as the case may be) of the casing terminating in the corresponding rib ot' taut casing. It is obviously desirable that such port-eontaining surfaces of the casing and measuring chamber shall fit Closely: for leaiv'age at this point will badly atieet the accuracy of the meter. It is clear that if there be such accurate fitting of the ribs of the measuring chamber to the ribs of the casing. that these port-containing surfaces of the measuring chamber and easing are held in close leakage-preventing contact by the mere fit of the measuring chamber ribs within the casing ribs, extreme accuracy of fit is required, and even then theconstruction cannot be satisfactory, because as pointed out hereafter. the casings of meters are somewhat liable to be distorted, hence causing the distortion of" the measuring chamber eloselv fitting the casing. In a -prior Patent No. 764,604, dated July 12,

1904, I have shown means whereby such extreme accuracy of fit between the measuring chamber and casing is avoided, a thrust screw or equivalent device being provided, on the side of the casing opposite that with which the n'ieasuring chamber'must make close connection, this thrust device tending to force the measuring chamber'over against that surface of the casing with which such measuring chamber must make a close lit, to prevent leakage at the joint. According to the present invention I employ, instead of such a thrust device, a screw, located in part in the said broad rib of the casing, and in part in the said broad rib of the measuring chamber, whereby those rib surfaces of the casing and measuring chamber which con.- tain registering ports, are drawn together. This construction has material advantages over the former construction referred to, as will be pointed out hereafter.

Mv' invention consists therefore in means for tlfiwingitogether the adjacent port-containing surfaces of the casing and measuring chamber, an'd.in other features all as hereinafter described and particularly pointed out in the appended claims The obiccts of my invention are to provide improved means for bringing and holding together in intimate contactthe port faces of the casing and measuring chamber, to pro viile easilv adjustable means for that purpose, to facilitate the fitting together and removal of the casing and'measuring chambe r, and to reduce the cost of manufacture.

l will now proceed todescribe my invention with reference to the accompanying drawings, and will then point out the novel features in the claims.v

In said drawings, Figure 1 shows a partial side elevation and partial central vertical section through the casing and measuring chamber. of a meter constructed in accordance with my invention. Fig. 2 shows a top view of the measuring chamber and lower section of the casing. a portion of the measuring chamber being broken away. Fig. 3 is a detail fragmentary vertical section through coacting ribs of the casing and measuring chamber. Fig. 4 shows a central vertical section of the measuring chamber and of a portion ofthe casing on the irregu-' lar line.X-X ofFig. 2. Fig. 5 is a top view of an alternative form of the lower section of the casing. Fig. 6 is a diagranr ma-tic view illustrating on a larger scale than the previous views. the difference of curvature of the abutting port-containing surfaces of the measuring chamber and casing. Fig. 7 is a fragmentary top view of the port-containing portions of the measuring chamber and casing, separated but closely adjacent one to the other.

' Referring first to Figs. 1 and Y, 1

designates the lower section of the casing of the meter, 2 the upper section thereof, 3 the inlet port of the casing, 4 the outlet port, 5' the measuring chamber (formed in two sect-ions as shown) and 6 the disk piston. The inlet and outlet ports of the casing are in spuds 7 and 8 respectively located diametrically opposite each other.

The casing is provided, internally, with three ribs, 9 and 1010, and the'measuring chamber is provided, externally, with three corresponding, ribs, 11 and 12 -12. It is desired that the surfaces of ribs 9 and 11 shall fit very accurately, but that there shall be clearance between 12 -12. In practice the interior of the casing and the exterior of the measuring chamher are bored and turned, respectively, initially, to nearly the same diameter (the measuring chamber being usually turned, as hereinafter explained, to a diameter slightly greater than the internal diameter of the casing), thus producing nearly the same curvature for the abutting surfaces of ribs 9 and 11; and then clearance is produced between ribs 1010 and 1212, either by dressing down the ribs 12-12 with a file or milling cutter or other convenient means, or, preferably after the casing has been bored to exact size, by shifting slightly thecenter of rotation of the casing or of the tool with which the casing is bored out, and taking another. cut from the surfaces of ribs 1010. InFig. 2 I have shown at 13, the true center of the casing, i. e., the centi from which the casing is boned-initially; and

r at 14 I have indicated the; eenter from which the further cut is takento give clearance beribs 10-10 and ribs' tween ribs 10 and 12. It will be understood that, for clearness of illustration, 1 have greatly exaggerated the distance between centers 13 and 14 and. correspondingly, have greatly exaggerated the clearance necessary between ribs 10 and 12; in practice the center H will require to be only from 5,-"1000thsto ll fllltlflths of an inch 0d the true center. This gives ample clearance for the easy insertion and removal of the measuring chamber.

To hold the surfaces of the ribs 9 and 11 close together. I provide, in the upper portion of rib a. a recess 15 toreceive. the head of a screw 16 screwing into a corresponding screw hole. in the rib 1.1 of the. n'ieasuring chamber. It will be obvious that by turning up this screw the surfaces of ribs 9 and 11 can be brought together very accurately, and held together firmly. The recess might be a blind recess, but in practice I prefer to have it a hole bored through to the port 4; leakage from the space above the measuring chamber through this recess '15 being prevented by a gasket 17 covering such recess member of the casing. corresponding in lo-v cation to the three ribs of the lower member of the casing; which gasket also forms a tight joint between the upper andlower sections of the casing. j

In some cases, particularly in large meters, instead of prOvidingcle-arance between ribs 10 and 12, clear to the bottoms of said ribs, :1 length from 1/16th to l/Sth of an and pressed down by the ribs in the upper inch at the bottoms of the ribs is left .with- In practice, and as indicated in Fig. 6, the

measuring chamber is bored to a diameter very slightly greater than that of the interior of the casing; the relieving of ribs 10 or 12, or both, nevertheless permitting the easy insertion of the measuring chamber into the casing. But because the port-containing surface of rib 11 of the measuring chamber is turned on a radius somewhat greater than that on which the port-containing surface of the rib 9 ofthe casing is bored, it follows that when these two port- .containing surfaces are registered, there iwill be tight contact at the edges of the ribs,- even though, there be slight clearance at int'erm'ediate points of these ribs. The clear- .ance at intermediate points does noharm,
